Methods for Evaluating Natural Experiments in Obesity: Systematic Evidence Review [Internet].

Obesity is an enormous public health problem among adults and children. Our objective was to systematically review studies evaluating programs and policies addressing obesity prevention and control in terms of their population-based data sources, use of data linkages, measures reported, study designs, and analytic approaches. The overarching goal of the review was to identify methodological advances that could strengthen research that uses natural experiments to evaluate the effectiveness of policies and programs to prevent and control obesity.
